Reporter: They're the reunions that capture our hearts. Soldiers returning home to their loved ones. And for the lotts family, their own homecoming just days away. I have a little countdown and every day I mark down one day closer. Reporter: Her husband, on a nine month deploit, separated by over 6500 miles. It's a trip I would also make. This is captain lotts' second deployment. Brittney gave birth to their first child, daughter finley three months ago. It's one of those things that you always think about that person is going to be there for, you know, but it's okay but it makes it a little bit -- just scary to do it alone. You only have the birth of your first child once, but america says that I need to be over here. So you know, they wouldn't call it service if it was easy. Reporter: Captain lots' job of clearing road side bombs is exceedingly dangerous work and a reminder of just how far away home truly is. I tell him, she's grown that much. I quit telling him because it kind of bums him out because he just feels like he's missing. Reporter: So we decided to bring a small piece of home to captain lotts here on the front lines. Hi, sweet heart, we're so excited to get you home. We're counting down the hours. Reporter: This, a first glimpse of a daughter her daddy has yet to meet. How is that? It's good. I can't wait to get home. Reporter: He and the rest of his division ready themselves for the final days in afghanistan and board their flight home, the realization just what is waiting for them on the other end of this journey.
